## 5功能实现代码讲解 ##

以添加一条配送员为例子，讲解jsp+servlet的整个过程。

### 5.1JSP页面 ###

**jsp页面内，以form表单的形式，action指向的地址为PsrServlet内的addPsr\_admin。并且在表单内，用户输入相应的数据信息。**

<form action="PsrServlet?action=addPsr_admin" method="post" id="registerForm" name="registerForm" >
                  <div class="layui-form-item">
                    <label class="layui-form-label">姓名:</label>
                    <div class="layui-input-inline">
    				<input name="psy" id="psy" class="layui-input" /> 
    				  <span id="msg3" style="color:red">${
        message}</span>
                    </div>
                  </div>
                   <div class="layui-form-item" >
                    <label class="layui-form-label">手机号:</label>
                    <div class="layui-input-inline">
    				  <input name="phone" id="phone" class="layui-input" /> 
                    </div>
                    </div>
                   <div class="layui-form-item" >
                    <label class="layui-form-label">登录密码:</label>
                    <div class="layui-input-inline">
    				  <input name="pwd" id="pwd" class="layui-input" /> 
                    </div>           
                    </div>
                        <div class="layui-form-item" >
                    <label class="layui-form-label">配送人住址:</label>
                    <div class="layui-input-inline">
    				  <input name="psrxy" id="psrxy" class="layui-input" /> 
                    </div>           
                    </div>
                
                  <br>
                    <div class="layui-form-item">
                    <div class="layui-input-block">
                      <button class="layui-btn" type="submit" id="sub_btn">提交</button>
                      <a href="PsrServlet?action=psrList" class="layui-btn layui-btn-primary" >返回</a>
                    </div>
                  </div>  
                  </form>

### 5.2Servlet.java ###

**在PsrServlet内定义addPsr\_admin方法**

if(action != null && action.equals("addPsr_admin")){
        
    				addPsr_admin(request, response);

**定义addPsr\_admin方法，先接受用户输入的数据，再调用set方法。并调用service方法，执行。在执行之前进行判断，如果改用户已存在，则提示信息，否则执行方法。**

private void addPsr_admin(HttpServletRequest request, HttpServletResponse response) {
        
    		String psy = request.getParameter("psy");
    		String phone = request.getParameter("phone");
    		String pwd = request.getParameter("pwd");
    		String psrxy= request.getParameter("psrxy");
    		Psr psr =new Psr();
    		psr.setPsy(psy);
    		psr.setPhone(phone);
    		psr.setPwd(pwd);
    		psr.setPsrxy(psrxy);
    		psr.setTime(new SimpleDateFormat("yyyy-MM-dd HH:mm").format(new Date()));
    		try {
        
    				Psr p1 = ps.selectPsr(psr);
    				if(p1 == null){
        
    					ps.savePsr(psr);
    					response.sendRedirect(request.getContextPath()+"/PsrServlet?action=psrList");
    				}else{
        
    					request.setAttribute("message", "该学生已是配送员,不能重复注册！");
    					request.getRequestDispatcher("/WEB-INF/views/register.jsp").forward(request,response);
    				}
    				}
    				catch (Exception e) {
        
    					e.printStackTrace();
    				}
    		
    	}

### 5.3Service.java ###

**定义service业务逻辑接口**

public interface PsrService {
        
    	void savePsr(Psr psr);
    }

### 5.4Serviceimpl.java ###

**继承接口，实现方法。也就是调用dao层的数据增删改查的方法。**

@Override
    	public void savePsr(Psr psr) {
        
    		 pd.savePsr(psr);
    	}

### 5.5dao.java ###

**dao层内，也就是数据访问层，定义SQL语句，执行插入语句。**

public void savePsr(Psr psr) {
        
    		try {
        
                runner.update("insert into psr (psy,phone,pwd,psrxy,time) values (?,?,?,?,?)",
                		psr.getPsy(),psr.getPhone(),psr.getPwd(),psr.getPsrxy(),psr.getTime());
            } catch (Exception e) {
        
                throw new RuntimeException(e);
            }
    	}
